Sound Processors for AV Receiver Systems
7.1ch Sound Processor
with Built-in Micro-step Volume
BD34705KS2
General description
The BD34705KS2 is an 8ch independent volume system.
The system is designed to allow 7.1ch surround system
application. It is improvement that sound quality more
than the conventional products. Micro-step volume can
reduce the switching pop noise during volume attenuation,
so a high quality audio system could be achieved.
8ch triple input selectors for zone 3 and multi channel
input enable the connection with a number of sources.
Features
 8ch input selectors
(It is extendable to up to 14 by other functions and
exclusion)
 Micro-step volume can reduce the switching pop
noise during volume attenuation.
 Zone 3 is supported.
 Built-in 2ch Volume for ZONE output
 2-wire serial bus control, corresponding to 3.3/5V.
Key Specifications
 Total harmonic distortion:
 Maximum output voltage:
